Member Data Documentation

format

VideoFormat format = VideoFormat::UNKNOWN

Video codec - VideoFormat::UNKNOWN if not (yet) determined.

fps

float fps = 0

Frames/sec, if known - 0 if not (e.g. not yet determined, or a VideoFrameSource that doesn't have a fixed rate).

frame_size

uint32_t frame_size = 0

Fixed size of a single frame in bytes - only meaningful for uncompressed formats (RAW/YUV422/RGB565/I420); 0 for compressed formats (H264/MJPEG/MPEG4), whose frame size varies per frame.

height

uint16_t height = 0

Frame height in pixels.

total_file_size

uint32_t total_file_size = 0

Total size of the container file/stream in bytes, if known. For DemuxerAVI this comes from the RIFF header's declared size (0 if the stream is unbounded/streamed). MP4 has no equivalent declared field, so DemuxerMP4 reports the number of bytes received so far instead (only equal to the true total once the whole stream has been fed in).

width

uint16_t width = 0

Frame width in pixels.
